It’s almost 20 degrees colder than the research says for chicks to be at one week of age.
Ginger walks around with a water resistant down coat which she can use at short notice to warm her brood.
Notice how wide apart her feet are? She can’t walk like this. However, it makes the base of her body much wider and thus provides more space for babies under her ‘down coat.’ Of course with only 4 bantam chicks she doesn’t need to do this to cover all of them, but it is instinctual and thus she will do it until they no longer need her to.
